Method and system for content sharing and authentication between multiple devices

摘要

A personal video recorder (PVR) enables delivery of audio-visual content and associated metadata to storage devices. The PVR is configured to access a plurality of services using a plurality of storage modules. Each storage module is dedicated to a single designated content provider. One or more of the storage modules are removably coupled to the PVR. A disconnected storage module can be reconnected to another PVR different from the PVR from which the storage module was disconnected. Where authorization is required to access content stored on the storage module, authentication is performed each time the removable storage module is reconnected to a PVR.

主权项

1. A method of accessing content data, the method comprising:
receiving a content data on a storage module of a first recording base station from a content source, wherein the content is encrypted and the storage module comprises a tuner dedicated to the content source; storing the content data on the storage module; transmitting an authorization request to an external authorization service, wherein the external authorization service validates the authorization request; receiving a first authorization key with the first recording base station, wherein the first recording base station accesses the content data on the storage module using the first authorization key and the first authorization key associates the content data to the first recording base station; removing the storage module from the first recording base station; connecting the storage module to a second recording base station; transmitting a second authorization request to the external authorization service, wherein the external authorization service validates the second authorization request; and receiving a second authorization key to the second recording base station, wherein the second recording base station accesses the content data on the storage module using the second authorization key and the second authorization key is specific to the second recording base station.
